What to look for in any research peptide supplier
Regardless of which supplier you choose, these criteria help evaluate transparency and reliability.
Independent third-party COAs
Look for certificates of analysis from a named, independent laboratory -- not just in-house QC. Ideally, each COA should be verifiable on the lab's own portal, not just a PDF the seller hosts.
Legal entity disclosure
A legitimate supplier discloses its registered company name, VAT number, and address. Anonymous sellers with no traceable legal entity offer no recourse if something goes wrong.
EU dispatch origin
For EU-based researchers, intra-EU shipping avoids customs declarations, potential duties, and border delays. Check whether the supplier names its dispatch country explicitly.
Independent review footprint
Trustpilot or similar third-party reviews provide an independent signal. On-site testimonials alone are less verifiable. Check whether the profile is claimed and actively managed.
